LEAKi-STOPPING DEVICE.

Appiicatigniiied July 7, `1925.` serial No. 42,064.

` This invention relates to ya device devised particularly for stopping a l'leak Vin a pipe such as is likely to loccur nio-re particularly where the ends of two pipe :sections arecoupled together.

Briefly, the invention is featured 4by the presence 'of a removable abutment placed on `one section of the pipe adjacent the 'leaky end of the coupling, -a gasket placed against the end of the coupling to stop the leak, and a means interposed between the gasket and vthe abutment, mand capable of compressing the 'gasket tightly against the, .end Vof the coupling to stop further leakage. Y

The object is to provide a simple and inexpensive device of this class which is easy to place in position for use, and onethat does not require the presence of bolts, nuts, and

the like to hold it in position on the pipe.

Other features and advantages of the invention will become apparent from the following description and drawing.

In the accompanying' drawing forming a part of this application and'in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a side view of a portion o a pipe showing two sections coupled together and indica-ting the position of the leak stopping device thereon.r

Figure 2 is a central longitudinal section taken approximatelyon the plane of the line 2 2 of Figure 1.

Figure 3 ris a cross section taken on the line 3 3 of Figure 1. Y

Figure 4 is a perspective kView of the so called abutment.

Referring to the drawings in detail, the reference character 1 designates one section of the pipe,2 the other section, and 3 the usual coupling or column which is threadedly connected to thev adjacent end. As stated, it is quite frequent for a leak to occur in the pipe particularly at theyoint. I am aware that numerous devices have been devised fory use at this point for stopping leaks of this kind, but so far as I have been able to ascertain, all of these devices are accompanied by objectionable parts. I therefore propose to provide avboltless device which may be easily applied so that packing may be clamped against either Aend of theV coupling to stop a leak. Y The improved device Vcomprises essentially what will hereinafter be referred to as an through slots Vsociet-ion with these keepers.

abutment et, together with a gasket 5 compressing means v6y for this gasket.

Considering lirst the abutment it will be seen that this comprises a pair of semi-circular lhalf sections 7, the adjacent ends of y and which are provided with outstanding ears 8,

the lower ones of which are provided with yUv-shaped keepers 9 extending upwardlyy in the upper ears. Removable lli-igs or Awedges 10 coopera te withthe keepers 14. The flanges 14 on the lower sections carrying U-shaped keepers 15 extending upwardly through slots in the flanges 13. Removable wedges 16 are also employed in asn Each half of the sleevel is provided with a central longitudinal rib 17 adapted to be gripped by a Spanner wrench or the likey whereby the sleeve may be bodily rotated with respect to the relatively stationary abutment. The sleeve is provided on the endv adjacent cams l1 with cooperating cams 18. More- 4Vand upper ears tocla-n'ip Vthe two pairs of the over, the sleevefis` formed with an internal annular rib 19 adapted to bear against compress the packing or gasketv 5. y

i In use, the abutment d is clamped upon the pipe at an appropriate distance from the and coupling, after which the con'ipressible packi ing ring (of split form) kis placed against the meeting end of the coupling. f Flien the rotary sleeve is placed in position to .surround the coupling and to bring the shoulder 19 against the packing with the cams 1S,

against the cams 11. Obviously, the cam action produced by the cooperating cam serves to bodily provide the sleeve against the packing and to compress it against the coupling to stop the leak.

A careful consideration of the description in connection with the drawings will enable persons familiar with devices ofthis kind will obtain a clear understanding of the in-y vention, for this reason a more lengthy description is tl'iought unnecessary.

Although the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coining` within the field of invention may be resorted to it desired.

Having thus described the invention, what l claim as new and desire to secure by Letters Patent is l, in combination, a pipe embodying a pair or sections, and a coupling connecting, said sections together, a compressible gasket placed againstcne end of the coupling, an abut-ment on one section of the pipe adjacent the gasket and spaced therefrom, relatively rotatable means interposed between the gasket and abutment, and cam coacting means between the rotatable means and abutment,

20 whereby the gasket will be `compressed when said means is rotated.

A leak stopping device Jfor pipe joints comprising an abutment adapted to be iixedly mounted on one section ot a pipe adjacent a leaking joint, said abutment embodying cams, aV sleeve adapted to encircle a coupling member of the joint, said sleeve being provided with a shoulder adapted to engage a gasket which is placed against one end olf said member, and coactingv cams en the sleeve cooperab'le with the iirst named cam.

As a new article of manufacture, a gasket compressing member for use in association with a leak stopping device ot' the kind described, comprising` a sleeve made up of two halves adapted to surround a pipe jointcoupling, said sleeve being provided with an internal annular rib to engage and compress a gasket against one end ci" said coupling, and a plurality ot' cams on one end ot' the sleeve.
